SM8450 (Snapdragon 8 Gen 1) and SM8475 (Snapdragon 8+ Gen 1) are high-end Qualcomm SoCs released in 2021 and 2022 respectively. SM7475 (Snapdragon 7+ Gen 2) is their upper mid-range equivalent and almost identical to SM8475. Internal msm codename for this platform is waipio. The board names are taro, cape and ukee. The three chipsets only have very slight differences in pinctrl and clock controllers.

WARNING: Even though SM8475 and SM7475 are almost the same as SM8450, the mainline kernel fork currently only includes very basic support for them! |
The chipsets have a lot of functionality already upstreamed by Qualcomm and more and more features keep getting submitted (for example, GPU support). It should be fairly easy to get basic functionality such as USB and UFS working to be able to use SSH to access the device.
A heavily work in progress mainline kernel is being developed here.
The following table serves as a rough overview of supported SoC features.
- Kernel release, e.g. v6.4: the feature was incorporated upstream as of this release.
- WIP: Feature works or works partially in community kernel fork. Not upstream yet.
- Y: The feature works with a generic or compatible driver.
- N: Feature is not currently supported.
- N/A: Feature might work, but has not been tested yet.
